DINSEN EN877 CI Cov Kav Dej Rau Kev Tsim Kho

Qhov Kev Sib Tw: Kev Xaiv Khoom Siv Hauv Kev Ua Dej Hauv Tsev Niaj Hnub

Thaum tsim cov tshuab dej hauv tsev nrog EN877 cam khwb cia hlau, cov engineers ntsib qhov kev txiav txim siab tseem ceeb. Cov yeeb nkab twg zoo tshaj plaws los sib npaug kev nyab xeeb hluav taws, kev tswj suab nrov, kev ruaj khov, thiab lub peev xwm ntws? Qhov kev txiav txim siab no tau dhau los ua qhov nyuaj dua thaum cov cai tsim kho hloov zuj zus thiab cov cuab yeej siv AI-powered procurement cuam tshuam rau kev xaiv cov khoom siv.

Rau DINSEN, cov lus teb yog meej: EN877-ua raws li cov hlau cam khwb cia dej ntws muaj kev ua tau zoo dua thoob plaws txhua qhov kev ntsuas dej ntws tseem ceeb hauv tsev.

Vim li cas EN877 Cast Iron Ua Tau Zoo Dua Li Lwm Cov Khoom Siv

Kev Nyab Xeeb Hluav Taws: A1 Kev Faib Tawm Tsis Kub Hnyiab

Hlau cam khwb cia yog cov khoom siv uas tsis kub hnyiab raws li ASTM E136. Nws siv tau rau hauv qhov chaw plenum yam tsis muaj kev txwv. Raws li tus qauv EN877: 2021 tshiab, cov kav dej ntws los ntawm hlau cam khwb cia yuav tsum siv cov txheej txheem uas tiv taus hluav taws A1.

A1 yog qhov ntsuas siab tshaj plaws. Qhov sib piv, PVC yog cov khoom siv hluav taws kub thiab xav tau cov khoom siv tiv thaiv hluav taws lossis cov dab tshos thaum nkag mus rau hauv cov khoom sib dhos uas muaj hluav taws kub.

Kev Ua Yeeb Yam Acoustic: Ua Tau Raws Li Cov Kev Xav Tau Suab Nrov Niaj Hnub

EN877:2021 tau qhia txog cov kev cai tshwj xeeb rau kev ntsuas kev ua haujlwm rwb thaiv suab rau cov kab ke dej ntws. Cov kav dej ntws los ntawm cov hlau cam khwb cia ua rau muaj kev txo qis suab nrov - qhov kev txiav txim siab tseem ceeb rau cov tsev nyob, tsev so, thiab tsev kho mob qhov twg kev nplij siab ntawm cov neeg nyob hauv tsev yog qhov tseem ceeb.

Kev Tiv Thaiv Kub

Khoom siv - Qhov kub siab tshaj plaws ntawm kev ua haujlwm tas mus li

EN877 Hlau cam khwb cia — 212°F (100°C) nrog ASTM C564 gaskets

PVC DWV -140°F (60°C)

Cov dej khib nyiab hauv chav ua noj feem ntau tshaj qhov txwv ntawm PVC txog 140°F, ua rau cov hlau cam khwb cia yog tib qho kev xaiv zoo rau kev ntws dej hauv chav ua noj ua haus.

Peev Xwm Nqus Tau: Kev Xam Xaj Raws Li Cov Khoom Siv

Kev nkag siab tseem ceeb los ntawm kev tshawb fawb IAPMO tsis ntev los no: cov khoom siv yeeb nkab cuam tshuam rau lub peev xwm ntws rau tib lub yeeb nkab loj. Ib lub 4-nti PVC ntsug stack muaj peev xwm ntws kwv yees li 429 gallons ib feeb, thaum tib lub yeeb nkab hlau cam khwb cia loj tsuas yog nqa 172.5 GPM - qhov sib txawv ntawm yuav luag 60%.

Qhov no tshwm sim vim yog:

• Cov ntaub ntawv sib txawv muaj cov kab sib txawv sab hauv
• Cov coefficients roughness sib txawv ntawm cov khoom siv
• Ntau cov cai plumbing siv cov lus qhia ntsuas qhov loj ntawm ib yam khoom yam tsis tau qhia meej tias yog dab tsi

Rau cov kws ua dej ntws: Cov hlau cam khwb cia muaj cov dej ntws ceev thiab tej zaum yuav xav tau cov kav dej loj dua PVC. Qhov no txhawb nqa cov txheej txheem txhim khu kev qha thiab pab tiv thaiv kev ua tsis tiav thaum ntxov. Kev ua tsis tiav thaum ntxov tuaj yeem tshwm sim thaum PVC yoog tau rov qab tsis zoo.

Lub Zog ntawm Cov Qauv: Cov Txheej Txheem Rigid vs. Cov Txheej Txheem Flexible

Hlau cam khwb cia yog ib lub kav dej khov kho uas muaj zog heev, txo qhov yuav tsum tau dai thiab ua rau poob tas li. Rau kev teeb tsa hauv av:

• Cov hlau cam khwb cia tsis xav tau cov ntaub pua chaw tshwj xeeb; hauv qab ntawm qhov tsuas yog yuav tsum ruaj khov
• PVC xav tau cov txheej txheem tshwj xeeb rau kev rov qab ua dua raws li ASTM D2321, suav nrog 4-6 ntiv tes ntawm cov ntaub pua chaw pw, compacted hauv 6-nti txheej rau 85-95% ceev
• Yog tias cov txheej txheem PVC uas yooj ywm tsis tau teeb tsa kom raug, lawv suav tias tsis ua haujlwm rau hnub thawj zaug ntawm kev pabcuam

Kev Ua Raws Cai ntawm Cov Qauv

Cov tshuab dej ntws DINSEN raug tsim tawm raws li EN877: 1999 + A1: 2006, tus qauv European uas siv rau cov kav dej hlau cam khwb cia rau cov tshuab tso dej tawm hauv tsev los ntawm DN40 txog DN600. Qhov hloov tshiab EN877: 2021 tshiab tshaj plaws tau nce qhov yuav tsum tau muaj zog tensile los ntawm 150 MPa mus rau 200 MPa.

Daim Ntawv Teev Cov Lus Qhia Txog Kev Tsim Kho Cov Dej Nqus Tsev

Thaum teev cov txheej txheem dej ntws DINSEN uas yog hlau cam khwb cia, xav txog cov kev teeb tsa no:

Cov Kev Cai ntawm Qhov Nce Toj (Kev Nqus Dej Los Ntawm Lub Zog)

Txoj Kab Uas Txoj Kab Uas Yuav Tsum Tau Ua

DN50 3.5% (35‰)

DN75 2.5% (25‰)

DN110 2.0% (20‰)

DN160 1.0% (10‰)

Qhov Chaw Dai Khaub Ncaws

• Cov kav dej kab rov tav: ≤2m
• Cov kav dej ntsug: ≤3m
• Yuav tsum muaj cov brackets uas muaj zog nyob rau hauv 500mm ntawm lub luj tshib thiab tees

Hom Kev Sib Txuas

• Hom W: Cov khoom siv sib txuas ua los ntawm cov hlau tsis xeb—zoo tagnrho rau cov haujlwm kho dua tshiab thiab cov chaw kaw (tsis tas yuav ua haujlwm kub)
• Hom A/B: Cov kev sib txuas flanged rau cov ntawv thov ruaj khov siab

DINSENmuab cov tshuab ua dej ntws uas ua raws li EN877. Nws tsim tau 1000MT ntawm cov yeeb nkab thiab 200MT ntawm cov khoom siv txhua hli. Tiv tauj peb pab neeg tshaj lij kom tau txais kev txhawb nqa tshwj xeeb rau qhov project.
